The functional groups contained in the illustrated antimalaria compound are that of the Hydrocarbon family.
(Lectures #7 and #8).

Aromatic Hydrocarbons (yellow)- Benzene derivatives with rings of six members and three double bonds. This structure is particularly stable due to it's bond arrangement.

Carboxyl Acid (red)- Strongly polar, therefore being highly soluble in water (hydrophilic). Some carboxylic acids are so "water-loving" that they are referred to as "miscible," (soluble in all proportions) in water.

Amides (green)- Proteins are made of long, complex chain-like structures of amides. Amides are derivatives of an acid with ammonia or the derivative of an amine (basic derivatives of ammonia).

The arrows displayed around the compound (Malaria 37 pdf, slide #1) show the strong polarity of each functional group, making the entire compound as well as it it's part highly water soluble. Through Hydrogen bonding, this compound can not only bond with water but can also bond with itself.
